After Emperor Wen ascended the throne, Queen Mother Bo became very sick and Emperor Wen accompanied her all the time, even if it meant that he could not sleep well. Sometimes he did not take his clothes off in the evening just in case she called for him. Every time after the herbal medicine was cooked, he would taste it first to make sure that it was not too bitter or too hot before letting his mother drink it.
Queen Mother Bo saw all of this, and her heart was deeply moved. She said to him, “My sickness will not go away anytime soon. We have many servants in the royal palace who can take care of me; you do not need to burden yourself.”
Upon hearing this, Emperor Wen kneeled in front of his mother and said, “If I do not personally take care of you while you are alive in this life, when will there be a chance for me to repay you for the grace of your parenting?”
Three years later, Queen Mother Bo gradually recovered. Everyone said that it was because of Emperor Wen’s wholehearted care. After that, people both inside and outside the royal court respected Emperor Wen even more. Everyone took him as an exemplar. During that time in history, everyone regarded filial piety toward parents as the most honored virtue.
